My CPU is reaching 98 degrees C on simples renders...

I just bought a new laptop - Predator Helios Neo 16, which I spefically bought because it's supposed to work well with Daz. However, the CPU temp is consistently reaching 98 degrees C for a simple render of a single G8.1F, despite it only being at 3% usage. The computer has an RTX 4060 with 8GB VRAM and Intel Core i9-14900HX. My previous computer only had 6GB VRAM and I never had this issue.

I have unchecked CPU in Daz render settings and unchecked CPU fallback. My scene only has 380,000 vertices in total. The render is fairly quick, about a minute, GPU usage is consistently in the high 90s during the render, I'm not sure if that's to be expected. The CPU temp stays in the mid-to-high nineties for the ENTIRE render as well. I've attached images for reference. I'm not a tech oriented person at all, so any help is super appreciated. Thanks a lot.

    That is odd ~ your CPU load is only 3% but temperature is 95 degree C... And without DS launched, the CPU temperature falls to normal level ?

    Suggest you verify the temperature info. again by using GPU-Z which is the only performance / thermal software that I trust.

    Hi thank you for your reply. Yes, when not rendering the CPU sits at about 50-54 degrees C. It also jumps up to 90 degrees or more when I open my Daz files, though it's only momentarily. I'm using PredatorSense, which is the built-in monitoring tool on the Predator Helios Neo 16. Will GPU-Z tell me my CPU temp? It sounds like it only focuses on the GPU.

    Yes ~

    I downloaded GPU-Z and get similar results. I tried rendering a scene with a single G8.1F, and while the render only took about 2 minutes, the CPU temp shot up to over 90 degree for the entire render process, and even reached 100 degrees several times. What kind of temperatures do other people's CPUs reach while rendering? I'm so baffled by this. This is a brand-new computer with what I thought were pretty good specs for running Daz.

    Oh, so ~ is there any cooling system with your CPU ?  If you just render with CPU, still the same result ?

    On my side, normally < 60 degree C when rendering with GPUs. My CPU is ADM Threadripper 3990x ~

    14900hx chips run very hot, so did the 13900hx.

    If the cpu and gpu cooling are shared, which is common, a high load on one will cause temps on the other to increase.

    The cpu will attempt to go as fast as possible while staying below 100c.

    Other peoples cpu temps won't tell you anything unless they have a similar laptop tp yours. Mine spikes to high 60s at the start of a render then drops to mid 40s, but it's a watercooled desktop pc.

    Make sure the vents on the laptop aren't obstructed.

    Try balanced mode instead of performance mode, it'll use less power for not much loss of real world performance.

    Take the fans off auto and try running them faster.

    If you're not satisfied with the resulting temps and fan noise return it and get a different model or a desktop.

    It's the strangest thing. I was originally in balanced mode and then started messing around with the settings after the CPU started overheating. Then after reading your message this morning I tried switching back to balanced again and BAM, problem fixed. The temperature is now maxing at 90 and averaging around 85 during the render. Still seems somewhat high but much better. I feel a bit dumb. Thanks a lot to both of your for your help!

    Ah... so Intel CPU per se is just the culprit ? ! Hmm, I didn't use Intel for many many years... this issue is still odd.

    I saw an interview with an Intel engineer where he said that unless you're close to the thermal limit you're leaving performance on the able. What he really meant was we're pushing these things hard out of the box because we're scared that AMD will be faster. The Intel defaults for my 13700K are 253w for an unlimted time period, which is silly. Performance mode using Intel's XTU software is 280w. Using the motherboard maker's recommended settings uses less power and attains higher speeds.

     You're welcome, and there's no need to feel dumb, the way these newer chips work is hardly transparent.

    You get a high power target for a short period, guessing 60-120 seconds for your chip. This helps with loading games, apps and starting a render for instance. During this period the cpu speed will drop to keep temps under the 100c limit.

    Then the power limit drops substantially and temps should settle. I think that because you were doing quick test renders you're in the higher power mode a lot causing the high temps. It's not an issue, it's how they're designed. By switching to performance mode you've slightly increased how much power the cpu can use at each stage and the temps increase in a corresponding fashion. Performance might increase with the extra power but in the real world it just makes it more likely to hit the thermal limit.
